VIII 12 inches. Near the eastern end of the quarry is 

 exposed another bed of limestone essentially like the last litho- 

 logically and containing similar fossils but with fewer individuals. 

 This bed constitutes the upper member of the limestone series, 



and from its light gray color, compact texture, and its many 



species of large fossils, it is strongly contrasted with the dark 

 Marcellus shale which overlies it. 



The fossils found in this bed are as follows:
